What have you done to try to fix the problem? Has the battery been replaced?
Thanks for using JustAnswer,Steve
There is a bulletin for a startup idle problem and it requires the power train control module to be reprogrammed.And if your vehicle is under 8 years and 80,000 miles the repair is free at the dealership.Here is how it reads.
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (PCM) with new software (Cal level 00Cal15C.).
2000 (TJ) Wrangler
2000 (WJ) Grand Cherokee
2000 (XJ) Cherokee
NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 4.0L (ERH)
ENGINE, CALIFORNIA EMISSIONS (NAE), AND CALIBRATION LEVEL PRIOR TO
(LESS OR LOWER THAN) THAT LISTED IN THE OVERVIEW ABOVE.
Some vehicle engines may exhibit a rough idle and/or MIL light "on" condition upon initial
start-up after a cold soak when temperatures are below 50 F (10 C).
There is also a possiblity that your "IAC" idle air control valve is stuck or binding.You can remove it from the throttle body and clean it with carb cleaner and try that.But usually they need to be replaced.

If I answered your question please accept.
If not please ask more questions. Happy holidays
With that many miles you will probably have to replace the iac,But cleaning it and trying is cheap.
Thanks and let me know,Steve
That sounds great.Thanks for keeping in touch.
Thanks for getting back with me.And I'm glad your problem is taken care of.
